Galerella pulverulenta

Cape gray mongoose

Features
By Sarah Gibbons

Geographic Range

Cape grey mongooses are endemic to southern Africa, ranging throughout the Cape provinces of South Africa, north into southern Namibia, and east to Lesotho and the Drakensberg range of western KwaZulu-Natal into Mpumalanga.

Habitat

Cape grey mongooses tolerate a wide variety of habitats, ranging from open country to semi-arid scrub forest to wet forest. They occur from sea level around the Cape provinces to an elevation of 1,900 m in KwaZulu-Natal. Cape grey mongooses frequent areas with dense bushes, rocky outcrops, and grass-covered boulders. They avoid areas with short vegetation. They are even abundant close to human settlements and are commonly seen on roadsides and under human structures.

Physical Description

Cape grey mongooses are small mongooses with long, slender bodies, long, bushy tails, and short legs. They weigh 490 to 1250 g, have a head and body length of 296 to 425 mm, and a tail length of 205 to 340 mm. Their long heads have pointed muzzles and small, rounded ears 15 to 36 mm long. Five digits are present on each foot, with the first digit reduced. Their claws are not well developed. Cape grey mongooses are speckled or grizzled gray in color, with legs and feet becoming darker distally. here is sexual dimorphism in body and skull size, with males being 1.24 times heavier than females.

There are three recognized subspecies of Galerella pulverulenta : G. p. pulverulenta , G. p. basuticus , and G. p. ruddi . Galerella pulverulenta basuticus is similar in appearance, but slightly paler in color due to its woolly underfur. Galerella pulverulenta ruddi has yellowish hairs with a darker underfur, making it appear brownish in color. The distal part of its tail is black.

Reproduction

Little information is known about mating systems in Cape grey mongooses. However, in other species of Galerella , males and females typically associate only for mating and males will seek opportunities to mate with multiple females.

Little information is known about reproduction in Cape grey mongooses. Pregnant females have been observed in August, September, and October, and lactating females have been observed in August, November, December, January, and February. The breeding season occurs at the end of the rainy season (from August to December). Various sites, such as rock crevices, hollow trees, and abandoned dens are used for breeding and rearing young. The maximum mass of a fetus is 20.2 g. Litters of 1 to 3 young are born fully furred with their eyes and ears closed. The young remain in the breeding dens until they are fully weaned.

There is little information available on parental investment in Cape grey mongooses. However, only females care for young in other Galerella species.

Lifespan/Longevity

There is little information available on longevity of Cape grey mongooses. Lifespan in the wild is believed to be 8 to 9 years. In the London zoo, one Cape grey mongoose lived for 8 years 8.5 months. Another individual lived for 11.7 years in captivity.

Behavior

Cape grey mongooses are diurnal, active shortly after sunrise until around sunset, occasionally resting around midday. They are generally solitary, although males do exhibit occasional sociality. Foraging behaviors include moving quickly between potential feeding sites (such as bushes), scratching the soil in search of prey under the surface, and throwing eggs backwards with the forefeet between the hind legs against a hard surface in order to crack them. They are terrestrial, but also able to climb trees. Fecal droppings are found singly or in small groups, typically close to sleeping sites. They do not use dens outside of the breeding season.

Home Range

Summer home ranges of Cape grey mongooses span from 0.21 to 0.63 square km. Ranges of females are smaller than those of males. Home ranges overlap greatly, both between and within sexes.

Communication and Perception

There is little information available on communication and perception in Cape grey mongooses. Sight and smell are important for foraging. Cape grey mongooses are known to sniff often when searching for food.

Food Habits

Cape grey mongooses are predominantly carnivorous, with small mammals, especially small to middle-sized rodents, being their primary prey. The rodents Otomys unisulcatus and Rhabdomys pumilio comprise the majority (>90%) of their diet in the West Coast National Park. Insects (especially coleopterans and isopterans ) are a secondary resource, constituting less than 5% of the diet. However, Cape grey mongooses are opportunistic hunters, and will prey on birds (mostly passerines ), reptiles , amphibians , eggs (mostly reptilian), arachnids , decapods , and mollusks , if accessible. They will also consume carrion and refuse when available.

Predation

There is little available information on predation of Cape grey mongooses. Predators may include larger predatory mammals, raptors, and snakes. In a 1980 study that surveyed nine martial eagle ( Polemaetus bellicosus ) nests, Cape grey mongooses comprised 0 to 25% (average 7.4%) of the prey collected. Anti-predator adaptations in this species are not well-known. When approached by humans in the West Coast National Park, Cape grey mongooses scurry into nearby thick bushes to seek shelter. They may also climb trees when threatened. In addition, their coat color blends well with the dominant color of their habitat, allowing them to move about discreetly.

Ecosystem Roles

Cape grey mongooses are used as a host by various arthropod parasites, including Echidnophaga gallinacea , Ctenocephalides connatus , Ctenocephalides felis , Procaviopsylla angolensis , and nymphs of Ixodes pilosus . In a 1990 study, scabies and ticks of unknown species were present on two of eight trapped Cape grey mongooses.

Commensal/Parasitic Species

Economic Importance for Humans: Positive

Cape grey mongooses help reduce rodent pest populations by removing a small proportion (less than 10%) of total rodent production.

  • Positive Impacts
  • controls pest population

Economic Importance for Humans: Negative

Cape grey mongooses are well-adapted to urbanization. They are frequently seen crossing roads, scavenging road kills and house garbage, and taking refuge under human structures, thus bringing them into conflict with humans. They are also known to take eggs and poultry when available.

  • Negative Impacts
  • household pest

Conservation Status

Cape grey mongooses are considered a species of Least Concern, as they are common throughout their range (densities reach up to 10 individuals per square km) and highly adaptable. They have a stable population with no major threats, and are present in a number of protected areas, such as the West Coast and Mountain Zebra National Parks.

Galerella pulverulenta is also known as Herpestes pulverulentus in the literature.
